Abstract: A multifunction car wash gun structure comprised of a car wash gun body, a connector, an adjustment mount, a sleeve, a setting sleeve, and a nozzle. The car wash gun body has a water passage formed inside and its top end extends forward. The connector is fastened to the top end and front extent of the car wash gun body and has a water passage formed inside that is in continuity with the water passage internally formed in the car wash gun body. Situated perpendicularly at the approximate center in the upper and lower ends, respectively, are two receptacles, and, furthermore, a through-hole of relatively smaller diameter extends through the center of the two receptacles. Two passages are formed through the approximate centers of the parallel two sides of the through-hole that are in continuity with the water passage within the interior section of the connector. A soap solution output hole of the water passage is situated in the lower receptacle. The adjustment mount is installed in the lower receptacle at the bottom end of the connector in continuity with the through-hole of relatively smaller diameter extending through the center of the upper and lower receptacles, at the upper extent of which is a soap solution output hole that is positionally coordinated with the output hole in the lower receptacle from the water passage through the interior section of the connector. The sleeve is filled with a soap solution and installed into the lower receptacle at the approximate center of the connector. The setting sleeve is installed into the upper receptacle of the connector and attached to the adjustment mount with a screw. The nozzle is attached to the front end of the connector. The major innovation of the invention herein is the assembly of a liquid wax chamber at the circumferential edge and then annularly attached between the end section of the connector and the car wash gun body, with the through-hole in the center of the two receptacles situated at the liquid wax chamber. Then, an output hole is formed, which in coordination with a mounting slot extending from the bottom section of the adjustment mount, enables the fastening of the sleeve. The soap solution output hole that is positionally coordinated with the output hole in the lower receptacle from the water passage through the interior section of the connector is situated on the center section and top surface of the mounting slot. The two passages at the center section of the through-hole are in continuity with the water passage within the interior section of the connector, and a curved flow channel is formed into one side and, furthermore, formed at the top end and at an appropriate position in the circumferential edge of the curved flow channel is a groove that is in continuity with the through-hole of the connector as well as the output hole of the liquid wax chamber, with a reverse profile washer mounted on its other side, thereby enabling the blockage of the water flow through the water passage internally formed in the car wash gun body and the contiguous water passage within the interior section of the connector at the end. Following completion of the assemblage of the present invention, the user can, in a manner that complies with ergonomic design and under conditions of more stability, directly rotate the adjustment mount to selectively control water flow stoppage, water-only output, combination water and soap solution output, and combination water and liquid wax output during utilization.
